The FAA and the National Transportation Safety Board were investigating the crash, the Arizona Daily Sun reported.
Pat Porter, a former 10,000-meter Olympian and 13-time distance runner national champion, married Olympic high jumper Trish King in 1991 after the two met during a pre-Olympic training camp for the 1988 Seoul Olympics, according to Trish Porter's website.
The couple moved to Albuquerque in 1994.
Dismayed friends and running enthusiasts remembered Pat Porter as an amazing distance runner.
"I'm just still in shock, I really am. He was a mentor for track and field and really cross-country," Stan Hockerson, the owner of Heart and Sole Sports, told KOAT.
